摘要

This paper is concerned with the recent trend of a research and development project of magnetic bearing control and its application for flywheel energy storage system. Some new results of magnetic bearing control system are described. Especially, a novel control method called zero power control is introduced. The zero power control means not only the zero bias current but also the zero control current for rotor near its equilibrium. The electromagnetic bearings are used for zero bias control as zero power nonlinear control. After the situation of the energy storage flywheel system is introduced, the application of the zero power control to the flywheel system for better efficiency of energy storage flywheel system is shown in this paper.
